Relying heavily on confidential industry research, the U.S. Environmental Protection Agency has proposed to re-approve glyphosate, the active ingredient in Monsanto’s Roundup.

EPA’s conclusion that glyphosate poses no risks to humans contradicts a 2015 World Health Organization analysis of the leading independent research that determined glyphosate is a probable carcinogen.

“American consumers have no reason to trust the EPA’s deeply flawed assessment of glyphosate’s safety,” said Nathan Donley, a senior scientist at the Center for Biological Diversity. “As with past EPA studies, the agency has relied heavily on confidential industry research that can’t be reviewed by independent scientists. This is an industry-friendly conclusion that’s simply not based on the best available science.”

In addition to the WHO’s conclusion, other U.S. federal agencies have acknowledged evidence of glyphosate’s link to cancer. This includes the EPA’s Office of Research and Development and the U.S. Department of Health and Human Services’ Agency for Toxic Substances and Disease Registry.
